A Midland bank robbery suspect allegedly stole money because of her addiction to crack cocaine, according to an FBI arrest affidavit released Friday morning.

Charlotte Denise Hemphill, 48, was arrested Thursday on a charge of robbery in connection with the incident that occurred Wednesday at Community National Bank in the 3300 block of Midkiff Road.

Hemphill, wearing a wig and sunglasses, allegedly walked up to a bank teller and handed a note that stated, “Put the hundreds in one envelope and put the fifty’s in the other and do as I said you don’t want me to hurt you!!”

She also displayed a handgun, which Hemphill told agents was a BB gun she purchased the day of the robbery.

After the robbery that occurred at about 2:15 p.m., Hemphill allegedly walked north, away from the scene. Video footage obtained by FBI agents revealed that Hemphill had parked her 2007 silver Mercedes-Benz in an alley behind the neighboring Woofers and Tweeters bar.

Agents determined her address on Thursday and saw her vehicle. An anonymous tipster later in the day gave the FBI Hemphill’s address and description of her vehicle, which confirmed what they already knew, according to the affidavit.

When Hemphill left her residence in the car, agents followed her to the parking lot of Albertsons in the 3300 block of Midland Drive. As she got out of the vehicle, agents arrested her.

Hemphill allegedly told agents that she did commit the bank robbery, used a BB gun, and did so because of her addiction to crack cocaine, according to the affidavit.

If convicted, Hemphill faces up to 20 years in prison, supervised release up to three years, a maximum fine of $250,000 and a $100 special assessment.
